8 If you say Y here (and to one of the following options) and create a
9 character special file /dev/watchdog with major number 10 and minor
10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
11 subsequently opening the file and then failing to write to it for
12 longer than 1 minute will result in rebooting the machine. This
13 could be useful for a networked machine that needs to come back

16 reboot the machine) and a driver for hardware watchdog boards, which
17 are more robust and can also keep track of the temperature inside

Linus Torvalds1da177e2005-04-16 15:20:36 -070020
21 The watchdog is usually used together with the watchdog daemon
22 which is available from
23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
24 also monitor NFS connections and can reboot the machine when the process
25 table is full.

42 The default watchdog behaviour (which you get if you say N here) is
43 to stop the timer if the process managing it closes the file
44 /dev/watchdog. It's always remotely possible that this process might
45 get killed. If you say Y here, the watchdog cannot be stopped once

696 ---help---
697 Hardware driver for the TCO timer built into the nVidia Hub family
698 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
699 watchdog timer that will reboot the machine after its second
700 expiration. The expiration time can be configured with the
701 "heartbeat" parameter.
702
703 On some motherboards the driver may fail to reset the chipset's
704 NO_REBOOT flag which prevents the watchdog from rebooting the
705 machine. If this is the case you will get a kernel message like
706 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

725 This driver can be used with the watchdog timer found on some
726 single board computers, namely the 6010 PII based computer.
727 It may well work with other cards. It reads port 0x443 to enable
728 and re-set the watchdog timer, and reads port 0x45 to disable
729 the watchdog. If you have a card that behave in similar ways,
730 you can probably make this driver work with your card as well.

733 it as a module. The module will be called sbc60xxwdt.

1036 Hardware driver for OCTEON's on chip watchdog timer.
1037 Enables the watchdog for all cores running Linux. It
1038 installs a NMI handler and pokes the watchdog based on an
1039 interrupt. On first expiration of the watchdog, the
1040 interrupt handler pokes it. The second expiration causes an
1041 NMI that prints a message. The third expiration causes a
1042 global soft reset.
1043
1044 When userspace has /dev/watchdog open, no poking is done
1045 from the first interrupt, it is then only poked when the
1046 device is written.
